LOOM-SI-IUTTLE.

To all whom it may concern Be it known that I, FRANK J. DU'roHnn, ofHopedale, l/Vorcester county, Massachir setts, have invented certain newand useful Improvements in Loom-Shuttles, of which the following is aspecification.

The present invention relates to the welt carrier holding springs ofshuttles used in automatic wetft-replenishing looms whereinreplenishment is effected by ejecting the spent \vei t carrier from theshuttle and in serting a. fresh weft-carrier.

It is old to employ for holding the weftcarrier a spring consisting oftwo inde iiendent resilient jaws which grasp the butt oi theweft-carrier on opposite sides; and the present improvement consists inthe means employed for maintaining such independent jaws in properrelative position.

The improvement is illustrated in the accoi'npanying drawings whereinFigure l, is a plan view of one end of a shuttle having one form of theimproved spring. Fig. 2, is a perspective of the spring shown in Fig. 1.Fig. 3, is a perspective of the shanks oil. a second form 01 spring.Fig. 4, is a similar perspective of a third form. F 5, is a section oithe shanks of a fourth term. F 6, is a side view 01 the form shown inFig. 5. i

As shown in Figs. 1 and 2, the weft-carrier holding shuttle springcomprises two independent grasping jaws A. and i3. having respectivelyshanks o, and Z), which are in contact with each other and fit a recessin the shuttle C, in the usual manner secured to the shuttle, ascustomary, by a hell I), passing through holes 0, in the shanks. it isvital that the two jaws should not turn on the bolt D, independently ofeach other. but should be locked one to the other. To this end the shanka, of jaw A has an extension (Z, which is folded around the square innerend of the shank Z), ofjaw B, and through this folded extension the bolt1). also passes. The two aws are thus mutually directly engaged andlocked together so that one can not turn on the bolt independently ofthe other.

In the form shown in Fig. 3, the shank b, of jaw B, has a right-angledopen recess (2, at its inner end, in which fits a rectangular stud f,bent and projecting laterally from the inner end of the shank a, of jawA.

In the form shown in Fig. l, the shank b. of jaw B, has a right-angledstud g,,p1.ojecting beyond its inner end which is straddled and fittedby two l'lat laced lingers I1, 71 stud f, bent and, projecting laterallyfrom the shank a, of jaw A.

in the form shown in l igs. 5 and (L the shank o, of jaw ll. has aplurality ol' reccsses i. surrounding the bolt hole r, which may extendeither partly or all the way through the shank. both ways being shown inFig. :3, the recesses being. however. on the inner face oil the shank.The shank o of jaw A, on its inner mating face has a plurality ofcorrespondinglv located laterally projecting studs Z, which closely litthe recesses 2', respectively.

In each of the several forms the two jaws are directly and mutuallylurked together by co-acting integral and reeiproca pro visions.

I claim:

1. A looni shuttle having a weft-carrier holding spring consisting oftwo separate and independent spring jaws having shanks which seatagainst iach other and are directly and mutually locked together byroacting integral provisions.

at loom shuttle having a well-carrier holding spring having two separateand independent spring jaws having shanks whit-h seat against each otherand are locked lo gether by mutually engaging integral projections andrecesses.

3. A. loom shuttle having a. weft-carrier holding spring consisting oftwo separate and independent spring jaws niul'uallv locked together bycoacting integral provisions.

A. loom shuttle having a weft-carrier holding spring having two separateand in' dependent spring jaws locked together by mutually engagingintegral projections and recesses.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
